www.npr.org scienceblogs.com Those who believe that humans are no longer evolving accept that we have variety. As pointed out above with the previous definition of evolution, we have 4.2 Amino Acid altering mutations every generation, and then we have genetic drift; it is entirely unreasonable to claim that we do not have variety between humans. What they do doubt though, is that there is any selective pressure left. They claim that due to the advent of modern medicine, technology, farming techniques, food distribution, heating and cooling systems etc, there are no longer any selective pressures in our lives to separate the fit from the unfit. The fitness differential is irrelevant in the environment that we have made for ourselves because we do everything we can to make sure ‘everyone’ survives. Additionally, even if some people die to unforseen virus or bacterial outbreaks etc, then although they may die, the reaction of medical intervention will be infinitely quicker than that of the evolutionary adaptation to the new selective pressure, and so no net evolution will actually occur. The capabilities within our modern society and the speed with which our culture adapts to change has completely overruled the process of natural selection and so stopped evolution.
There are several problems with these claims. These problems can be placed into several classes of error including;
Misunderstanding the nature and power of Natural Selection,
Forgetting other forms of selection, such as sexual selection,
Assumptions about the entire world from the specific first world lifestyles of the very people claiming this, and
Mistakenly taking the term ‘current evolution’ to mean that evolution must happen before our eyes.
